Choosing 2700X Motherboard - X470

[blootrix]

Heyo, thanks in advance for helping out.
(LOCATED IN THE UK) On Black Friday / Cyber Monday I'm upgrading my PC.

CPU - 2700X for streaming, gaming & editing.
RAM - I've settled on 2x8GB Corsair Vengeance LPX 3200MHz, I would have gone for G.Skill Trident 3600MHz, but it's £125 vs £210 respectively.
Cooler - Cryorig H7 / Noctua NH-D15, I'll decide once I know what motherboard I'm going for.
I can't decide on what motherboard to get, I've read a TON of posts and I still can't decide. Right now I'm looking at:

£100 - Asus Prime Pro X370
£160 - Asus Prime Pro X470
£135 - Gigabyte Aorus Ultra Gaming X470
£165 - Gigabyte Aorus Gaming 5 X470

My budget is £170 max.
Is the Asus Prime Pro X470 worth 37.5% more than the X370 version?
Asus Prime Pro X470 or Gigabyte Aorus Gaming 5 X470?
Would the Gigabyte Aorus Ultra Gaming X470 be a better choice that sits right in the middle?
I know there are a bunch of MSI boards, such as the X470 Gaming Pro, but I've not heard anything great about them.

For future upgradability, I only looked at motherboards that have:

64GB Max RAM
2x PCI-E X16 Slots
2x M.2 Ports

I'm not sure if I'll ever overclock the 2700X. I've read that the 2700X is a very poor overclocker, 4.2GHz is the best I can hope for (even though it's advertised as 4.35Ghz?) and in a lot of cases the CPU will overclock itself better than a bog standard overclock would anyway, is this correct? Added to that, is there any point in getting anything better than a basic X470 board?

Thanks again in advance!

First of all, X370 Boards are very simlar to X470s, but don't have a future upgrade path.
The Ultra is also similar to Gaming.

Try to look at Strix board or (my personal choice) Aorus Gaming.
